For sale today is this super cool and rare Ricoh riquartz. Ricoh was one of the first producers of quartz watches in the 70s, and they developed and produced their own quartz movements. This piece is from the Early 70s and features the early version of the Ricoh Cal 590 with the ceramic PCB. It also features a hammered finish on both the dial and case similar to many Seikos from the era. The watch was recently serviced (by me), and it runs well with normal consumption. Case: 37x38x10.5. Silver case (unknown purity) with stainless steel back. Some scratches and dents consistent with age. Moderate tarnish on the silver parts.
